There are three levels of settings:
Global settings Global settings are the default settings of the application. They are used if no other settings are available.
Group settings Group settings are applied to all profiles in a group. They overwrite global settings. E.g. for a specific group of servers to overwrite the SSH key file or Windows credentials.
Profile settings Profile settings are applied to a specific profile. They overwrite group settings. E.g. for a specific server to overwrite the SSH key file or Windows credentials.
The priority is as follows:
Global settings (default) → Group settings (overwrites global) → Profile settings (overwrites group)
